When replacing a component identified with, use only the replacement parts designated, or parts with the same ratings or resistance, wattage, or voltage that are designated in theparts list in this manual. Leakage-current or resistance measurements must be made to determine that exposed parts are acceptablyinsulated from the supply circuit before retuming the product to the customer.Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are calledElectrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field effect transistors andsemiconductor chip components.The following techniques should be used to help reduce the incidence of component damage caused by static electricity.1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any electrostatic charge onyour body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging wrist strap device,which should be removed for potential shock reasons prior to applying power to the unit under test.2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such as aluminum foil, toprevent electrostatic charge build-up or exposure of the assembly.3. Use only a grounded-tip soldering iron to solder or unsolder ES devices.4. Use only an anti-static solder removal device. Some solder removal devices not classified as anti-static can generate electrical chargessufficient to damage ES devices.5. Do not use freon-propelled chemicals. These can generate electrical change sufficient to damage ES devices.6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it. (Most replacementES devices are packaged with leads electrically shorted together by conductive foam, aluminum foil or comparable conductive material.)7. Immediately before removing the protective material from the leads of a replacement ES device, touch the protective material to thechassis or circuit assembly into which the device will be installed.Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion such as the brushing togetheror your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity sufficient to damage an ES devices.CAUTION :harman/kardonAVR 139-141-142/230 Service ManualPage 2 of 83RadioFans.CN 收音机爱 好者资料库223ENGLISHTechnical Specifications for AVR Surround ReceiverTECHNICAl sPECIfICATIoNs foR AVRAudio Sectionstereo Mode Continuous Average Power (fTC) 40 Watts per channel, 20Hz20kHz, 0.07% THD, both channels driven into 8 ohmsfive-Channel surround Modes Power Per Individual Channel, all channels driven simultaneously front l&R channels: 35 Watts per channel, 0.07% THD, 20Hz20kHz into 8 ohms Center channel: 35 Watts, 0.07% THD, 20Hz20kHz into 8 ohms surround channels: 35 Watts per channel, 0.07% THD, 20Hz20kHz into 8 ohmsfive-Channel surround Modes (one channel driven into 6 ohms, 1kHz, 0.07% THD) front l&R channels: 70 Watts per channel Center channel: 70 Watts surround (l & R) channels: 70 Watts per channelInput sensitivity/Impedance linear (High level) 200mV/47kohmssignal-to-Noise Ratio (IHf-A) 95dbsurround system Adjacent Channel separation Analog Decoding 40db (Pro logic, etc.) Dolby Digital (AC-3) 55db DTs 55dbfrequency Response 1W (+0db, 3db) 10Hz100kHzHigh Instantaneous Current Capability (HCC) 25 AmpsTransient Intermodulation Distortion (TIM) UnmeasurableRise Time 16secslew Rate 40V/secFM Tuner Section frequency Range 87.5108MHz Usable sensitivity IHf 1.3 V/13.2dbf signal-to-Noise Ratio Mono/stereo: 70/65db (DIN) Distortion Mono/stereo: 0.15/0.3% stereo separation 35db 1kHz selectivity 400kHz: 70db Image Rejection 80db If Rejection 90dbAM Tuner Section frequency Range 5221620kHz signal-to-Noise Ratio 45db Usable sensitivity loop: 500V Distortion 1kHz, 50% Mod: 0.8% selectivity 10kHz: 30dbVideo Section Video format PAl/NTsC Input level/Impedance 1Vp-p/75 ohms output level/Impedance 1Vp-p/75 ohms Video frequency Response 10Hz8MHz (3db)General Power Requirement AC 230V/50Hz Power Consumption 72W idle, 580W maximum (2 channels driven) Dimensions (Max) Width 440mm Height 165mm Depth 382mm Weight 9.6 kgDepth measurement includes knobs, buttons and terminal connections.

After the pause, reconnect the ACpower cord and check the units operation. If thesystem still malfunctions, a system reset mayclear the problem.To clear the AVRs entire system memory including tuner presets, output level settings,delay times and speaker configuration data, firstput the unit in Standby by pressing the SystemPower Control button 1. Next, press andhold the Surround Mode Button 6for 5 sec-onds.The unit will turn on automatically.Note thatonce you have cleared the memory in this man-ner, it is necessary to re- establish all system configuration settings and tuner presets.NOTE: Resetting the processor will erase anyconfiguration settings you have made for speakers, output levels, surround modes, digitalinput assignments as well as the tuner presets.After a reset the unit will be returned to the factory presets, and all settings for these itemsmust be reentered.If the system is still operating incorrectly, theremay have been an electronic discharge or severeAC line interference that has corrupted the memory or microprocessor.If these steps do not solve the problem, consultan authorized Harman Kardon service depot.SYMPTOMCAUSESOLUTIONUnit does not function when No AC Power Make certain AC power cord is plugged Main Power Switch ?is pushedinto a live outlet Check to see if outlet is switch controlledDisplay lights, but no sound Intermittent input connections Make certain that all input and speaker or pictureconnections are secure Mute is on Press Mute button 4 Volume control is down Turn up volume controlSound is heard, but Front-Panel Display brightness is turned off Follow the instructions in the Display Brightness section Display does not light on page 23 so that the display is set to VFD FULLNo sound from any speaker; Amplifier is in protection mode Check speaker-wire connections for shorts at receiver light around Power switch1is reddue to possible shortand speaker ends Amplifier is in protection mode Contact your local Harman Kardon service depotdue to internal problemsNo sound from surround or Incorrect surround mode Select a mode other than Stereocenter speakers Incorrect configuration Check speaker mode Stereo or Mono program material With (analog or digital) Dolby surround modes, the surround decoder may not create rear-channel information from non-encoded programs Speakers not properly connected Check speaker-wire connections or use test toneto verify connections (see page 20)Unit does not respond to Weak batteries in remote Change remote batteriesremote commands Wrong device selected Press the AVR selector ?
